Disadvantages
- Confusing billing practices and unexpected charges: One of the most frequent complaints from customers is the lack of transparency in iolo’s billing practices. Several users have reported being charged for services they did not sign up for, or being billed before their subscription expired. This lack of clear communication can create confusion, especially for long-time customers who expect predictable costs. For instance, some customers experienced automatic renewals at higher rates, causing frustration and inconvenience
- Slow scan speeds: While iolo's antivirus does a good job of detecting and removing threats, their full system scans tend to be slower than some competitors. Some users have noted that full scans can take over an hour, which may be frustrating for those who require quicker results. This could be an issue for users who are looking for a fast, efficient solution without having to wait long for a full scan to complete
- Exclusivity for Windows: iolo’s antivirus and optimization tools are exclusively available for Windows, which limits their utility for Mac, Linux, or other operating system users. Additionally, iolo is not available on mobile devices, whether they run Android or iOS. This lack of cross-platform support can be a disadvantage for individuals or businesses with a diverse range of devices. While iolo provides excellent protection and performance features for Windows users, those who rely on other operating systems will need to consider alternative solutions for their security needs
- Upselling during customer support calls: Another recurring issue is the aggressive upselling tactics used during customer support interactions. Many users expressed dissatisfaction when technicians tried to sell them additional services or upgrades while they were seeking help with basic issues. This can make the support experience feel less customer-focused and more like a sales pitch, detracting from the trust and satisfaction customers expect from technical support
- Limited independent testing: Despite their strong feature set, iolo's antivirus protection has not been extensively tested by independent labs like AV-TEST or AV-Comparatives, leaving some questions about their effectiveness in comparison to other antivirus software on the market. Without this independent validation, users may feel uncertain about the true reliability of their malware protection compared to other top-rated products
Customer Experience
iolo Technologies has received an overall positive feedback from users, holding a score of 4.1 out of 5 on Trustpilot. Many customers appreciate the quality of the support, the effectiveness of the products, and the responsiveness of the tech team. However, there are some recurring issues regarding billing practices, upselling, and customer support experiences.
Positive feedback
Customers frequently praise iolo's responsive and knowledgeable customer support.

Many reviews highlight the effectiveness of the system optimization tools, with customers reporting noticeable improvements in system speed and performance after using System Mechanic. Users also appreciate the helpfulness of the support team, especially when solving technical issues or guiding them through setup processes.
Critical feedback
While many reviews are positive, there are some complaints from users about billing practices. Several customers reported unexpected charges, issues with auto-renewals, and difficulties receiving refunds. For example, one customer mentioned being charged for a service they never subscribed to and having trouble getting a refund. Another user expressed frustration with being charged higher prices without prior notice, leading to dissatisfaction with the company's transparency. Additionally, some users mentioned long wait times for support or communication lapses regarding their service issues. A few also noted that upselling during support calls detracted from their overall experience.
Proactive approach
iolo has been proactive in addressing many of the complaints, especially those regarding billing issues. The company often responds to negative feedback, apologizing for any misunderstandings and offering to resolve the issues directly. In some cases, they have escalated the matter to higher management or provided direct contact to ensure that concerns are properly addressed. They have also assured users that they are working to improve their communication and refund processes, especially around auto-renewals. However, the company’s efforts are sometimes perceived as inadequate, particularly in cases where multiple customer support interactions are required to resolve issues.
